Biography
Dr. Bohumir Jelinek is a physicist and HPC software developer with an educational background that includes scientific formation from American and European universities. He holds a PhD in Physics with a minor in Mechanical Engineering and an MS in Computer Engineering from Mississippi State University. At present, Dr. Jelinek works on vehicle dynamics, control systems, numerical models for off-road mobility, and simulations of solidification and additive manufacturing. His expertise includes interatomic potential development for material science, numerical modeling of Yagi-Uda antennas, development of automatic speech recognition systems using neural networks and hidden Markov models, discrete element/lattice-Boltzmann method for large particle assemblies in fluid, visualization, MPI parallelization, and deployment of container technologies for HPC applications. He is a member of International Society for Terrain-Vehicle Systems.

Research Interest
Off-road Mobility
Journal of Terramechanics 2025 and ISTVS 2023 articles on wheel performance in sand, ISTVS 2021 publication on contact forces and stress calculations in soil under wheel load
Ground-vehicle Control Systems
GVSETS 2024 article on vehicle-level control systems, including ABS
Vehicle Dynamics
GVSETS 2021 paper on suspension tuning
Additive Manufacturing
Implemented 2D thermal finite element model (2d-heat-ded on GitLab) of directed energy deposition additive manufacturing process (animations) in Python using FEniCS framework. The model matched pyrometer measurement of melt pool length and was presented at FEniCS'19 conference and published in the Journal of Manufacturing Processes.
Particle Motion in Fluids
Parallelized 3D LBM code for partially saturated computational cells, coupled with Discrete Element method (summary), featured in MSU headline news, HPCwire 2016 and in 2017 brochure of The Coalition for Academic Scientific Computation, pp. 17.
Alloy Solidification
Parallelized 2D and 3D alloy solidification code (JCP article with source code, presentation), achieved a landmark featured in the 2012/09/19 HPC research spotlight.
XSEDE - single largest Mississippi allocation in 2013
Electrokinetic Phenomena
Revealed Charge density effects on the nanoflow (DOI), presentation, animated pressure equilibarion.
Density Functional Theory, Molecular Dynamics
Developed a MEAM potential for Al, Si, Mg, Cu, and Fe alloys (included in a NIST database), PRB journal article - results reproducible with Python
Speech Recognition using Hidden Markov Models
Worked on ISIP ASR system, sample C++ code and documentation.
Numerical modeling of EM field
Implemented open-source Yagi and log-periodic antenna simulation package which can be downloaded from https://github.com/bohumir/yagi-logper. Yagi-logper reads a Yagi or Logper antenna from it's own-simple-input-format file or from a minimal-featured NEC2-formatted file. It then calculates the currents along the dipoles and the antennas' radiation pattern. For a use with GUI, Yagi-logper can be executed from Antennavis software package, where it acts as a replacement for nec2. Yagi-logper does not offer all features of NEC2, however, it is more accurate in a limited domain of symmetric dipole arrays, such as Yagi and Logper antennas, in a free space (no ground). In Antennavis GUI, the user can adjust locations and dimensions of the dipoles after reading the initial configuration from the NEC2-formatted input file, execute yagi-logper (which acts as nec2) substitute, and visualize the antenna radiation pattern in 3D.
